Mapping between spectra variables and data file fields

The spectraVariableMapping function provides the mapping between spectra variables of a Spectra() object with data fields from a data file. Such name mapping is expected to enable an easier import of data files with specific dialects, e.g. files in MGF format that use a different naming convention for core spectra variables.

MsBackend() implementations are expected to implement this function (if needed) to enable import of data from file formats with non-standardized data fields.

Usage

spectraVariableMapping(object, ...)

spectraVariableMapping(object, ...) <- value

# S4 method for class 'MsBackend'
spectraVariableMapping(object)

# S4 method for class 'MsBackend'
spectraVariableMapping(object) <- value

# S4 method for class 'Spectra'
spectraVariableMapping(object) <- value

# S4 method for class 'Spectra'
spectraVariableMapping(object)

Arguments

object

An instance of an object extending MsBackend().

...

Optional parameters.

value

For spectraVariableMapping<-: a named character vector.

Value

A named character with names being spectra variable names (use spectraVariables() for a list of supported names) and values being the data field names.
